OSi’s Role in National Mapping
Maintain and develop the underlying physical infrastructure of the State which is needed to support
mapping applications.
We create consistent and homogenous, maintained digital databases.
We provide similar information across the entire country, which enables government, businesses and individuals, the ability to create policies, operations and expectations of a countrywide
nature.

Important part of State infrastructure adding value to key national projects:
Irish Water Property TaxSeptic Tanks
Postcodese-Government Strategy 2012 – 2015
INSPIRE Directive
Knowing where something is protects its value & makes possible the integration of data from different government departments for
effective planning and decision making.
Location Matters to Government

Planning Applications, Roads, Housing, Heritage, Engineering works etc.
• Better Citizen Services: Powerful tool for demonstrating and analysing the physical evidence of issues.
• Better Resource Optimisation: common referencing framework for all.
• Better Decisions: Rapid access to up-to-date information across organisation & public.
• Slide 5

Archaeology - Hill of Ward“Birthplace” of Halloween
• Research by Dr Steve Davis UCD• Despite the presence of an important 'royal' site at the
hill's summit, the known archaeology of the area immediately surrounding the hill is sparse. Only two extra sites have been previously recorded
• It was anticipated that analysis of LiDAR coverage from the area might bring to light previously unidentified low-profile archaeological features and so enhance the archaeological understanding of landscape in the vicinity of the hill itself.– More archaeology then previously thought.– Previous interpretations of the site itself are both corroborated
and questioned

Paper Digital PC /Server Web Any Device
Practically overnight, access to terabytes of geographical information, much of it in three dimensions, has changed the way
people work, live and entertain themselves.
The industry is changing …. fast

Prime 2A new spatial database to meet current
and future demands
• Industry standard spatial data storage model that allows digital spatial information to be stored and managed effectively in relation to the OSi authoritative digital reference mapping.
• A database of real world features derived initially from multiple current sources.
• Seamless, scale independent, object based spatial data management infrastructure.
• The most significant revision to OSi’s data management and product generation process in over 30 years.
• Completed and available by June 2013.
![Page 26: OSi Local Gov User Group Presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558a16acd8b42acf028b46dd/html5/thumbnails/26.jpg)
Why?Industry Requirement for..
• Open and Robust Data Model– To be used across a variety of systems
• Consistency– Logical, Thematic, Temporal,
Attribution• Integrated
– Coping with many types of spatial data• Representative
– Models the world in a more intuitive and logical way
Rigorously based on industry standards:
• Data model > OGC Simple Feature Model
• Metadata > ISO 19115• Roads > GDF standard• 3D > ISO CityGML Level
2• Supply > GML data &
OGC compliant web services
![Page 27: OSi Local Gov User Group Presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558a16acd8b42acf028b46dd/html5/thumbnails/27.jpg)
Prime 2 Enables…
• Link objects using persistent ID (GUIDs) • Use Form and Function classifications• Build Relationships buildings / way• A metadata rich storage model from which a multitude of
products can be automatically generated.• Full networks connectivity (roads, water)
– Road centre line GDF1 & GDF2– Distinguish road surface, paved areas, grass verges
• New supply possibilities– Develop schemas to suit your needs
• Manage change only data
![Page 28: OSi Local Gov User Group Presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558a16acd8b42acf028b46dd/html5/thumbnails/28.jpg)

Benefits
• Achieve higher data quality levels• Implement new products and services• Allow for more effectively management of data• Metadata is captured not only at the dataset level or the
individual object level, but down to the individual attribute level.
• Allows the user to “graft” their own data on to the new model
• Meeting the challenge of “Shared Services” – Water Charges– Household Charges– Septic Tanks– Lighting

MapGenie Overview• Award winning web based
mapping services that allow users to connect directly to OSi’s national map database online
• Data can be used in standard Geographical Information System (GIS) software, or it can be used in web or mobile applications.
• Standards based with open format
• Designed to deliver rapid, easy access to map data and aerial imagery

Model for future?
OSi acts as a trusted custodian for spatial data, stores it centrally and serves it back to Local Authorities or centralised Local Authority applications.

Where to next for OSi?
![Page 36: OSi Local Gov User Group Presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558a16acd8b42acf028b46dd/html5/thumbnails/36.jpg)
Public Sector Reform
• Merger Process on-going• Working Group Report June
2012• Cabinet decision thereafter
![Page 37: OSi Local Gov User Group Presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558a16acd8b42acf028b46dd/html5/thumbnails/37.jpg)
What can OSi do - Reduce, Move, Create
1. Continue to reduce our operating costs so we can reduce licence costs
2. Move as many services and deliveries online – so we increase efficiencies
3. Move up the GI value chain (enhanced web services)
4. Create the environment within which the benefits of authoritative, maintained and consistent spatial asset is fully recognised.
![Page 38: OSi Local Gov User Group Presentation](https://reader035.vdocument.in/reader035/viewer/2022062419/558a16acd8b42acf028b46dd/html5/thumbnails/38.jpg)
OSi manages national coverage large-scale topographic data, which is a national asset and
resource delivering value for money to the State, private enterprise and citizens.
